Title: Sequential signal transmission system - has equispaced switching facilities along preset path allowing access for sending commands at constant speed and timed spacing
Inventor: NIESSEN GUENTHER
IPC: H04N13/30
Filed: 1991-02-15
Abstract: The signal segmential transmission system provides switching facilities along a preset path at equidistant spacing. On impingement or deblocking, at an end, a device switches forward the contact poles at a preset and constant velocity. Thus, on an instruction, the forward switching is carried out at identical time intervals. Accordingly, pulses are generated at regular intervals, as long as a transverse path is not blocked in-front of or behind the switching point. Thus binary signals in bit pattern form, can be transmitted by blockage and deblocking of the process. The binary signals may have the form of black and white, or colour image points. USE/ADVANTAGE - Transponders radiating e.g. object number etc. for radio labels, with simple and low-cost design, and improved versatility; e.g. for remote registration of identification number of credit or cheque guarantee cards, price tickets on identified goods preventing theft, electronic flash reader for laundry marks large animal tags buried under the skin.
